Abstract

Additive manufacturing and subtractive manufacturing combined machining equipment comprises an additive manufacturing device, a cleaning device, a subtractive manufacturing device and a transferring device, wherein the additive manufacturing device comprises an energy source mechanism and a forming mechanism; the forming mechanism comprises a forming cavity and a forming substrate arranged in theforming cavity; the energy source mechanism is used for forming powder on the forming substrate, so that a semi-formed workpiece can be obtained, the semi-formed workpiece on the forming substrate issubjected to repeated forming, and a formed workpiece is obtained; the transferring device is used for transferring the forming mechanism and the workpiece on the forming substrate, and transferring is performed between any two of an additive manufacturing work position, a cleaning work position and a subtractive manufacturing work position; the cleaning device is used for cleaning the workpiece on the forming substrate; the subtractive manufacturing device is used for machining the workpiece on the forming substrate. According to the equipment, subtractive manufacturing can be combined between the semi-formed workpiece and the formed workpiece of additive manufacturing, inner and outer surfaces of the semi-formed workpiece can be subjected to subtractive manufacturing timely and accurately, and the applicability and the machining efficiency of the formed workpiece are improved.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a composite processing equipment for adding and subtracting materials. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, is different from the traditional processing mode of removing, cutting, and assembling raw materials. It is a "bottom-up" manufacturing method through material accumulation. Generally, after adopting additive manufacturing to form an integral part, it is necessary to perform subtractive machining processes such as milling to remove machining allowances or polishing surfaces. However, the workpieces formed by additive manufacturing, especially those with complex structures, are difficult to be processed by subtractive material on the inner surface, thus limiting the applicability and processing efficiency of the formed workpieces. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a composi...
